| Title | Failure to Identify and Correct a Condition Adverse to Fire Protection |
| Description | The inspectors identified a finding of very low safety significance and an associated non-cited violation of Waterford Steam Electric Station, Unit 3, License Condition 2.C.9, and the fire protection program for the licensees failure to identify and correct a condition adverse to fire protection. Specifically, the inspectors identified that the ventilation dampers that are used to maintain the environmental conditions of the No. 2 diesel fire pump room and that are needed for pump protection were damaged and not functional for an extended period of time. As a result, the reliability of the No. 2 diesel fire pump could have been impacted at high environmental temperatures. The licensee entered this condition into their corrective action program as Condition Report CR-WF3-2015-00132. The licensee manually opened the dampers and additional planned corrective actions included repairing the broken dampers linkage before the temperatures outside reach 90oF. This performance deficiency was determined to be more than minor because if left uncorrected, the performance deficiency had the potential to lead to a more significant safety concern. Specifically, if left uncorrected, the licensees failure to repair the damaged ventilation damper in the No. 2 diesel fire pump room would result in an ongoing degraded condition, which could have impacted the capability of the No. 2 diesel fire pump to fulfill its function of providing a water supply to the sites Fire Protection Systems. Using Inspectional Manual Chapter 0609, Attachment 4, Initial Characterization of Findings, the inspectors determined that the use of Inspection Manual Chapter 0609, Appendix F, Fire Protection Significance Determination Process, was required because the finding involved fixed fire protection systems. Using Inspection Manual Chapter 0609, Appendix F, Attachment 1, Fire Protection SDP Phase 1 Worksheet, the finding screened as Green because the reactor would have been able to reach and maintain a safe shutdown condition. Specifically, since only the No. 2 diesel fire pump was impacted by the performance deficiency, the No. 1 diesel fire pump and the motor driven pump would have been able to supply the fire systems because they are all rated for full flow capacity. This finding had a cross-cutting aspect in the area of human performance, avoid complacency, because individuals did not recognize and plan for the possibility of mistakes, latent issues, and inherent risk, even while expecting successful outcomes. Specifically, licensee personnel frequently tour the fire pump house for operations and maintenance activities; however, a thorough review of the work site had not been performed [H.12]. |
